Weitec springs and shocks i just took off my car worked pretty well
The big problem with your question is that "comfort" is subjective, depends on what you think is comfortable.
Lowering is done for looks. It should be no surprise that this generally makes the handling worse.
Done properly, a lowered car can be comfortable, handle well and look better than the standard model.
It is generally agreed that for pure track handling, the Mk.IV Golf platform needs to be raised at the front and lowered at the back. Many enthusiasts with lowered suspension will be screeching right now, but it's true.
Lowering means stiffening, and less roll in corners, which can feel better. Lowering also means reduced suspension travel, and so is more likely to result in lifting the inside wheel, which is bad for grip. In real handling terms, nearly all lowered cars are worse off.
My TDI Toledo has the Sports suspension package, which is lowered 15mm on Bilstein dampers, and has stiffer anti-roll bars front and back. It's hugely better than my old TDI 110 with the Comfort suspension, but that's mostly down to the improved anti-roll, and the fact that I'm driving in traffic on public roads and not on the track.
In the end you have to work out your own compromise.
Body roll is controlled by anti-roll bars which improve your comfort around fast bends but make the ride worse over potholes and speed bumps.
The problem with lowering the Mk.4 platform is that the roll center is lowered by twice as much as the center of gravity. So you have actually increased the roll moment, made it want to roll more in corners. This can be countered by stiffer anti-roll bars, but at a cost to comfort, and with the eventual consequence of lifting the inside wheel when you push it too far.
The aerodynamics of the bodyshell are largely unaffected by ride height, as the underside is not panelled or shaped at all. An air dam at the front will help to reduce front-end lightness at high speeds, but the difference would not be felt at most road speeds, unless you're heading into a gale force wind.
Racetracks tend not to have potholes or other lumps and bumps, so track cars can be set up with ground-skimming skirts and air dams - not an option we have, running on public roads. They can have much stiffer anti-roll bars too, as the driver's comfort is not a selling point.
Given that the state of much of our road network is poor, we need to consider good handling over bumps and potholes as well as on smooth surfaces, which leads us towards rally-car suspension i.e. more travel, less anti-roll stiffness and increased ride height. In practice this means that lowering, if taken to extremes, will result in a car that handles badly over anything other than a smooth road - and there aren't many of those around.
In my case I'm very impressed with the Sport suspension on my Toledo, and wouldn't want to spend money to change it.
Consider replacing worn suspension bushes if the car has some mileage on it. That on its own can sharpen up handling and improve the feel no end.
A rear ARB will make a big difference and reduce a lot of the under steer.
Damian @ DPM Performance
ARB's would be best but also would be a good time to fit new bushes.
Once their done then ytou can fiddle with different suspension option to fine tune ride height and handling characteristics
The rear ARB I have is Neuspeed.
This is the only one you can fit if you have an OEM lum.
As for Powerflex v's Superpro, dunno min.
I got superpro as i got them from Keith at http://unit-15.com/
3mm???
LOL
I've got a 28mm and never had any issues with it.
I had an S3 front upper strutt brace fitted at the same time and the handling was good.
I went for Eibach pro kit springs becasue I was after pretty much everything you are and so far I'm really pleased, slightly lower improved dynamics and not too bad ride comfort.
